Modified bikes divide opinion. Some riders see them as labours of love; others see red flags. But what really matters when it comes time to sell?
Whether you’re tricking out a track weapon or customising your daily ride, mods can either increase your motorbike’s resale value or sink it. In this guide, we look at which upgrades help you sell faster and for more – and which ones can actually harm your chances of shifting it.
Factory vs. Aftermarket: Why Buyers Care
Most buyers like things clean, simple, and predictable. When a motorbike has been modified, it introduces uncertainty: Was it done well? Is it still road legal? Has it been thrashed?
What buyers worry about:
- Legality of the modification
- Impact on insurance premiums
- Wear and tear from aggressive riding
- Loss of manufacturer warranty
- Whether they’ll need to reverse the mod
That doesn’t mean all mods are bad. Some upgrades are seen as tasteful and desirable. The key is doing the right mods, and doing them well.
Mods That Boost Resale Value
Some modifications can make your bike more attractive to buyers, especially if they improve comfort, performance, or practicality without turning it into a Frankenstein machine.




Top resale-friendly mods:
- Heated grips: A big win for UK riders, especially commuters.
- Quality aftermarket exhaust: Brands like Akrapovič or Yoshimura can add performance and appeal if fitted correctly.
- Crash protection: Frame sliders, engine guards, and bobbins can show you’re a careful owner.
- Upgraded seat: Touring comfort mods are a plus, especially on cruisers and adventure bikes.
- Luggage systems: Panniers, tail bags, and top boxes make bikes more versatile.
- Touring screens: For naked and touring bikes, a taller screen can be seen as practical and desirable.
These types of mods can help your bike stand out without alienating buyers. Just make sure everything is professionally installed and well maintained.
Mods That Hurt Your Resale Value
Here’s where it gets tricky. Mods that are too extreme, taste-specific, or poorly done tend to scare off potential buyers or lower your selling price.



Common mods that can reduce value:
- DIY paint jobs: Unless you’re a pro, leave it to the pros.
- Custom LED lighting: Mood lights under the tank? Cool for you, not for most buyers.
- Lowered suspension: It may suit your build, but limits appeal and often compromises handling.
- Race-spec tuning: Power commanders and dyno maps scream “I rode it hard.”
- Shorty levers, bar-end mirrors, tail tidies: Not inherently bad, but often done cheaply and badly.
- Chopped frames and hardcore café racer builds: Stylish? Maybe. Sellable? Rarely.
The problem with these mods is that they’re highly personal. What one rider loves, another might hate. And more often than not, a buyer will use them to haggle you down.

Tips for Selling a Modified Bike
If your bike has mods and you want to sell it for the best price, take these steps to keep your resale strong:
- Keep the original parts! Being able to return the bike to stock is a major bonus for buyers.
- Document every mod. Receipts and service history help build trust.
- Be honest in your ad. Don’t hide mods, highlight the good ones and explain why they matter.
- Get it serviced before selling. A recent check-up goes a long way with buyers.
- Consider parting out high-value mods. You might earn more selling them separately and returning the bike to stock.
